Although blocked drains can occur at any time of the year, the problem is usually more common during winter, especially in colder temperatures. Blocked drains are one of the most frequent plumbing issues faced by people in both residential and commercial properties.
When a drain becomes blocked, it often causes stress and confusion until the issue is resolved. While emergency plumbing services are available to fix the problem, many winter drain issues can be avoided by taking a few simple precautions.
Here are four common mistakes that lead to blocked drains in winter and how to avoid them.
1. Ignoring Heater Settings
One of the most common mistakes that can lead to blocked drains in very cold weather is not setting the heating system correctly. It is generally recommended to keep indoor heating set to at least 55°F (around 13°C).
Keeping temperatures too low can allow water inside pipes to freeze, which may lead to blockages, restricted flow, or even pipe damage.
2. Skipping Maintenance Checks Before Winter
Ignoring regular maintenance checks is another common reason for blocked drains. Even if drain inspections are not carried out throughout the year, it is important to check the condition of your drains before winter begins.
Issues such as grease build-up, foreign objects, or tree root intrusion may already be narrowing the pipes. During winter, natural contraction of pipes can further restrict the flow, increasing the chances of blockages.
A simple pre-winter drain inspection can help identify and fix small issues before they become major problems.
3. Not Insulating Outdoor Pipes
Leaving outdoor pipes exposed without proper insulation can become a costly mistake. These pipes are directly exposed to cold temperatures, which can cause water inside them to freeze.
Frozen water can expand and lead to pipe blockages, cracks, or leaks. In some cases, this may even cause structural damage. Properly insulating or covering external pipes helps prevent freezing and reduces the risk of blocked drains.
4. Pouring Excess Grease and Oil Down the Sink
Kitchen drains are among the most commonly blocked during winter. Colder weather often leads to more home cooking, which means more oil, fats, and grease going down the sink.
These substances can solidify inside the pipes, especially in lower temperatures, and gradually cause blockages. While cooking more in winter is natural, small precautions can help — for example, occasionally pouring warm water down the sink to prevent grease build-up.
One simple habit can help avoid major plumbing problems.
